DISK FOR REFRIGERATlNG AND HEATING PIPES.

SPECIFICATION forming part of Letters Patent No. 440,671, dated November18, 1890.

Application filed January 13, 1888. Serial No. 260,676. (No model.)

To (tZZ whom it may concern:

Be it known that 1, PETER WEISEL, of the city and county of Milwaukee,and State of Wisconsin, have invented certain new and usefulImprovements in Disks for Refrigerating and Heating Pipes; and I dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it pertains to make and use the same. reference being hadto the accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

The objects of my invention are to increase the radiating orheat-absorbing surface of heating or refrigerating pipes or coils, tofacilitate the attachment or removal of disks to or from such pipes orcoils, to simplify and cheapen the construction of such disks, &c.

It consists, essentially, of a disk formed with a central perforationopen on one side to receive the pipe and with key-seats, and a keyadapted to said seats and arranged to draw and secure the disk snuglyupon the pipe.

In the accompanying drawings like letters designate the same parts inthe several figures.

Figure l is a perspective view of my improved device and a portion of apipe to which it is attached. Fig. 2 is a cross-section of the sametaken axially through the pipe, and Fig. 3 is a perspective view of thekey.

Pipes or coils employed for the circulation of a coolingmedium,particularly gases-such as ammonia-gas-which are worked underhigh pressure, require strong tight couplings which it is not desirableto disturb. same time it is desirable to increase the efficiency of suchpipes or coils and to prevent the accumulation of ice thereon byproviding an additional radiating orheat-absorbing surface. with acentral perforation to receive the pipe 0, and a lateral slot or openinga into said central perforation to permit of its being placed upon orremoved from said pipe without disturbing the latter or its couplings.Said disk is provided around its central opening with a hub or flanges aa, adapted to present a broad surface in contact with the pipe. Theedges of the disk on each side of the lateral At the To this end Iprovide a disk A, formed opening or slot 0. are preferably stiffened byflanges a a, forming continuations of the hub or flanges a a around thecentral perforation.

B is a key concaved to fit over a portion of the pipe 0, and formed atthe edges with tapering tongues adapted to engage tapering dovetailedgrooves or seats a formed for that purpose in opposite sides of thecentral opening or hub a. a, ofthe disk A. The disk A is readily placedupon a pipe which enters the central perforation through the sideopening a. ,and the keyB inserted through said opening, and its taperingtongues b I) forced into the similarlyshaped seats a draws the concaveportion of said key and the hub a of the disk snugly against the pipe.The disk may be as readily detached and removed from the pipe byremoving said key B.

I claim- 1. The combination, with a pipe, of a disk having a lateralslot or opening for the reception of the pipe and transverse grooves onopposite sides of said opening, and a key adapted to engage said groovesand secure said disk upon said pipe, substantially as and for thepurposes set forth.

2. The combination, with a pipe, of a metallic disk formed in a singlepiece with .a lateral slot and transverse tapering grooves on each sideof said slot, and akey having tapering tongues on its sides adapted toengage said grooves and secure said disk upon its pipe, substantially asand for the purposes set forth.

3. Th e combination of a disk having a semicircular seat and a slotextending therefrom through one edge of the disk with seats in theopposite edges of said slot, and a concaved key adapted to be insertedin the direction of the axis of said disk in the seats formed in theopposite edges of said slot, substantially as and for the purposes setforth.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

PETER WEISEL.
